SPECIFICATION forming part of Letters Patent No. 375,830, dated January 3, 1E83.

Application filed October 19, 1886. Serial No. $216,655.

To all whom it may concern:

Be it known that I, WILLIAM F. OLIN, of Chicago, Cook county, Illinois, have invented certain new and useful Improvements in Self- Binders, of which the following is a description, reference being had to the accompanying drawings, making apart of this specification.

Referring to the accompanying drawings, Figure l is a rear elevation of a binding-machine having my improvements incorporated therein. Fig. 2 is a top plan View of thesame, the deck, breast-plate, and other parts foreign to my invention being omitted. Fig. 3 is a side elevation of aportion of the clutch mechanism.

[5 Fig. 4 is a top plan view of the same. Figs. 5

and G, a side view and a top plan view of details of the clutch-tripping devices.

Referring to the drawings, A is the binderframe of the well-known Appleby type liav zo ing horizontal arms at the top and bottom to support the knottcr drivingshaft A and the needlccarrying shaft A2. The needlecarrying shaft Ai has at one end a fixed-crank, A".

The knotter-shaft A has fixed on its rear end the gear A*, provided with a wrist or crank pin, A5, which is connected by a p itman, B, with the crank of the needle-shaft, so that at each revolution of the gear A* the needle receives an upward and downward vibration, as

3c in existing machines.

O represents the horizontal crank-shaft, by which the packers are carried as usual. This shaft is mounted in suitable bearings in the frame and will receive a constant rotation through driving mechanism of anyappropriate character.

D is the trip and compressor-shaft mounted horizontally in bearings in the frame and provided with the trip and compressor Dand with 4o a crank,Dat the rear end, both parts being fixed rigidly thereon. The gear A4 is formed with an irregular cam, E, on its side face. This cam engages and moves an anti-friction roller, F2, mounted on one end of an arm,F, pivoted to the frame at the point F lying between the frame and the gear A4. The relative positions of the cam and the wrist A5 are such that during the advance of the needle the compressor is elevated and moved toward the same to assist 5a in the compression of the gavel, and inally (No model.)

at the proper time the compressor is released and permitted to fiill in order that the bundle may escape, these actions being essentially the same as in other machines already known in the art.

In order that the compressor lnayoppose the needle elastically or with a yielding resistance, Iprovide the moving end of the lever F with a socket or barrel, F3 containing and supporting one end of a spiral compres 6c sion-spring, F. The upper end of the compressor operating pitman G is jointed to the lower end of the stem or spindle F5, which is extended upward through the barrel and the spring, and provided at its upper end with a nut, F6, bearing on the spring and serving as a means for regulating its tension, so that the compressor may be sustained with more or less force, as the character of the grain may demand. Vhen the compressor meet-s with 7o excessive pressure, the spring F4 will yield, and, allowing the pitman G to descend, will permit the retreat ofthe compressor.

The pitman G is preferably formed with a lateral wrist at its upper end, extending through and beyond the spindle F5, for connection with the tripping devices, as will be presently explained.

The packershaft C, as before mentioned, is driven constantly, and is provided with a 8o sprocket-wheel, C', connected by an endless chain, C", with a second sp1ocket-\\-'heel, C, mounted on a stud, O5, on the binder-frame, and receiving a constant rotation. On the stud or axis ofthe pinion C3 is mounted loosely 85 a pinion, H, which engages and communicates motion to the main gear A". The pinion H carries the dog H', pivoted thereto. This dog has a shoulder, against which the semi-friction rollers H2, mounted on the sprocket- 9o wheel O3, engage when the parts are in operative position. The dog is acted upon by a spring, H4, which has a tendency to keep it in position to engage the rolls. When thus engaged, the dog communicates motion from the sprocketvwheel to the pinion H, and thence to the main gear and knetter-shaft in a familiar manner.

My devices for permitting the above clutch ing devices to be engaged at proper intervals ico A gear A* remain at rest.

and to be disengaged at proper times differs from the others at present known in the following particulars:

I-ivoted to the main frame, preferably concentric with the arm F, is the detent I, adapted to reach upward and engage the outer end of the dog or pawl H and throw the same out of engagement, in order to stop the motion of the pinion H. The detent I has an arm eX- tended rearward beneath the knotter-driving shaft A', terminating in the foot I', which underlies a cani, I2, formed on the hub of the main gear A4. The detent I is also formed with a second arm, I3, extending rearward and pivoted upon thejournal which connects the pitman G to the spindle F5.

The operation of these parts is as follows: The rotation of the packer-shaft C causes the packers to com-pact the gavel against the compressor D2, while the pinion II and the main The compression of the accumulating gavel against the compressor D2 forces thelatter backward, and, rocking its shaft D, causes the arm D to pull the pitinan G downward against the resistance of the spring F4. The pitman in its descent acts,

'through the arm I3, to throw the detent I out of engagement with the dog H', whereupon the dog, engaging one of the rollers on the wheel C3, causes motion to be transmitted through pinion II to the main gear A4 and its cam. The rotation of the main gear through the parts before described causes the needle to be brought forward and the compressor to be advanced in the opposite direction. As the pinion H makes four revolutions while the gear A4 makes one, the detent I must be retained in such position that the dog H will not strike it and disengage the clutch until the pinion has completed its fourth revolution, so as to complete the binding operation. The rotation ofthe gear A'1 causes its cam I2 to bear on the foot of the arm l of the trip I and hold it down, and thus it is that the detent is kept out of action. At the termination of the binding operation the cam I is carried clear ofthe detent, and the latter, under the action of the spring, disengages the clutch mechanism.

In order to keep the binding mechanism in its normal position and prevent the wheel A4 from starting back ward,as it frequently occurs with this form of clutch, I mount the springactuated pawl K on the wrist A5 of the main gear, the form and proportion of this pawl being suoli that when the gear A' reaches the l proper position of rest the dog falls behind and bears against the axis C5 of the pinion H, as shown in Fig. 1.

I am aware that grain-binding. machines driven through a clutch which was disengaged by a detent have been provided with automatic means for holding the detent ont of action until the completion of the binding action; but I believe myself to be the first to mount a cam on the shaft of the main gear-wheel and arrange it to act on the detent.

Having thus described my invention, what I claim is l. In a grain-binder of the Appleby type having an overhead knotter-driving shaft, the combination of the main gear-wheelA, dxed on tlieknotter-shaft, its driving-pinion H, the continuously-rotating driving-wheel G3, concentric with the pinion, the clutch devices to connect the driving wheel and pinion, the detent I, to hold the clutch out of action, and the cam I2, carried by the knotter-shaft, and acting directly on the detent to hold it out of engagement with the clutch, whereby the knotter-shaft is enabled to vdirectly control the period of action of its driving-clutch.

2. The gear A4, mounted on the knotter- .driving shaft, the driving-pinion engaging directly therein, and the continuously-rotating driving-wheel C3, concentric therewith, in combination with the clutch-dog to connect said wheels, the clutch-tripping arm I, acting at one end directly on the dog, the compressoroperating spring acting directly on the arm to cause its engagement, and the cam on the knotter-driving shaft also acting directly on the arm to hold it out of engagement.

3. The detentl, having arm I3, and the stem or spindle F5, and its encircling spring, in combination with the positively-actuated compressor actuating lever F', sustaining the spring, and the compressor-pitman connected at one end to both the lever and the detent.

4. The compressor operating lever, the spring receiving support therefrom, and the stem or spindle passing through the spring, in combination with the detent-lever I, and compressor-actuating pitman having one end connected with both the stem and the detent by a single wrist or journal.
